Machined to fit seamlessly while bringing both artistry and rugged engineering to John Browning's classic 1911 design, the Crimson Trace LG-919G Master Series Lasergrips is sure to impress. Featuring ergonomic and aggressively durable G10 black side panels with a rubber overmolded activation button, these are the ultimate laser sights. Standard to Crimson Trace Lasergrips, the LG-919G features Instinctive Activation. This means that the laser sight automatically springs to life when the weapon is held in a natural firing grip. Master Series Lasergrips are fully compatible with ambidextrous safeties.
